The S&P 500, a key benchmark for U.S. large-cap stocks, is experiencing a robust bull market in 2024, with the index climbing over 20% as of now. However, this surge is not equally distributed among all companies, leading to increased market concentration. This article explores the current landscape of the S&P 500, the implications of money supply trends, and potential investment strategies.
Uneven Participation in the Market Rally

While the overall index shows significant growth, the rally is heavily driven by a select few companies. Notably, over 20% of the S&P 500’s value is attributed to just three giants: Apple, Microsoft, and Nvidia. The top ten stocks account for approximately 35% of the index’s total value, a concentration not seen since the 1960s. This rising dominance of a handful of megacap stocks raises concerns about the sustainability of such concentration in the long term.
Understanding Market Concentration and Its Implications
The increasing concentration in the S&P 500 suggests that as these large companies grow rapidly, smaller firms may struggle to compete. Historically, high market concentration can lead to inefficiencies and less competition, which could stifle innovation and growth in the broader market. However, economic indicators suggest that a shift may be on the horizon.
The Role of U.S. Money Supply in Stock Performance
One key factor influencing market dynamics is the U.S. money supply. A healthy money supply can stimulate economic growth by providing businesses with easier access to capital. When the money supply is tight, smaller companies often find it challenging to access the resources needed to thrive. Recent data from J.P. Morgan indicates a correlation between the growth rate of the money supply and stock market concentration.
Following a period of tightening monetary policy, U.S. money supply growth is now accelerating. After a significant decline in 2023, M2 money supply— which includes cash, deposits, and other liquid assets—has shown positive growth, reaching 2% year-over-year in August 2024. This change is largely attributed to the Federal Reserve’s recent interest rate cuts, which are expected to facilitate borrowing and stimulate growth, particularly for smaller companies.
Investment Strategies Amid Changing Economic Conditions
As money supply accelerates, it could signal a potential turning point in market dynamics, allowing smaller companies to gain traction. Investors looking to capitalize on this trend have several strategies at their disposal:
1. Equal-Weight Index Funds
One effective way to invest in a potentially less concentrated market is through equal-weight index funds. The Invesco S&P 500 Equal Weight ETF (RSP) is a prime example. Unlike traditional cap-weighted indexes, this fund allocates an equal amount of capital to each constituent, allowing for a more balanced exposure across the index. As larger companies face challenges or underperform, equal-weight funds may provide better returns.
2. Small-Cap Stocks
Another strategy involves investing in small-cap stocks, which are not included in the S&P 500 but often face similar challenges. Small-cap stocks may experience substantial growth as market conditions improve, especially if they can access capital more easily. The S&P 600 Small Cap Index, which tracks 600 of the smallest U.S. companies, represents a promising avenue for investors looking for value. The SPDR Portfolio S&P 600 Small Cap ETF (SPSM) offers a low expense ratio and focuses on profitable businesses, potentially mitigating some risks associated with smaller companies.
The S&P 500’s bull market in 2024 reflects significant gains driven by a few dominant players. However, with changes in the money supply and the potential for smaller companies to thrive, investors should remain vigilant and consider diversifying their portfolios. By focusing on equal-weight index funds and small-cap stocks, investors can position themselves to benefit from a more balanced and resilient market landscape as economic conditions evolve.
Looking Ahead
As the market continues to shift, staying informed about economic trends and adjusting investment strategies accordingly will be crucial for long-term success. The current climate presents both challenges and opportunities, and those who adapt may find significant rewards in the coming years.
